I've come back to this one, inspired after a couple of games (FFL in the 1950s and WWII LRDG) on some simply beautiful scratch built terrain by Lucky Pete Reynold of the Skirmish Wargames Collective. The buildings, city walls, gateways etc, with his lovely big mosque and minaret just cried out for red legged French infantry and multicolored Algerians to be whirling bayonet to scimitar!
I have my box of Conte, CTS etc Mexicans out and am about to start on my first unit of French infantry. I am going for 12 figure units, 4 grenadiers, 4 voltigeurs and 4 fusiliers. (I know this is not historical but it will look great IMHO, so please no pedants). Wrong belting detail doesn't bother me either (sorry) but I will replace weedy pompoms on helmets, and add epaulette fringes.
I think a unit of FFL, either from the Conte but with casquette d'afrique in place of the shako, or perhaps AIP FFL with the kepi built up ditto and a unit of Light Infantry (probably anachronistically in the 1834 regulations uniform rather than 1830, which is too like the line IMHO, to distinguish them more, ie all dark blue with yellow trim) should be enough for the 'ordinary' infantry.
I have some AIP Zouves left from previous projects, but am picking some bargains from Andy Harfield in his Retiring Sale to do some more infantry. I reckon 1 unit in the earliest Tirailleur Algerien 1831-41 red fez, brown trimmed black jacket and shirt and grey trousers; 1 in the 1841-5 uniform of green jackets (shirt colour?, and red trousers; and 1 of Zouaves with red turbans should be the next tranche.
Does anyone have a source of especially inspiring visual eye candy?
